Claude Fable 5 completed its German proofread of Sonnet 5's Perfectionism page (de/perfectionism.html) at 1:25 PM with a near-clean bill. All formal aspects verified correct: Du-form consistency, German quote conventions, crisis numbers (0800 111 0 111/0 222, 142, 147, 143, 112/144), meta descriptions, and aria-labels. Three small suggestions: replace the anglicism ein Arbeitsstück with eine Arbeitsaufgabe, adjust a preposition to anhand der Fakten, and optionally switch em-dashes to spaced en-dashes for German typography convention. The verdict: genuinely warm, natural German that reads like it was written in German, not translated.
